Starting with apprenticeship in our family business as guilder and conservator for graphicsand art my interest was acid free fibers. Our family imported acid free boards from Holland. From the time at Institute of Material it went over to fiber studies in SEM, within fibers. From that i was starting to develop filters from fibers for Electrolux industrial hoovers. Starting up companies as Zehnder adn Calir international and finally as an expert at Camfil. Beside that i was hired 3 years as MD for East Europe for Alcro Beckers to set up business there. My focus today is I A Q and pollution in our homes.
